BLANK.

SPECIFICATION forming part of Letters Patent No. 768,124; dated August 23, 1904, Application filed February 4, 1904. Serial No. 192,028. (N model.)

ing-machines, such as are adapted to have let-- ters or characters formed in relief thereon.

The objects of my invention are, first, to supply a blank that is reversible as to the side to be presented to the die or matrix, and, second, to form the blank so that the impressing of the die will form theletter full in relief.

My invention consists in the peculiar construction of theblank whereby the above objects are attained, all of which will hereinafter fully appear, and be particularly pointed out in the claims.

In the drawings, Figure 1 is a view illustrating a blank subject to and being operated upon by a die, illustrating the peculiar'adaptation of the blank for machines of this type. Fig. 2 is a crosssectional view of the blank, illustrating the construction or formation of the same more clearly and partly stamped, so as to throw the letters in relief. Fig. 3 is an isometric view of a blank.

In forming the blank, which is made of duetile metal, and preferably aluminium; I form the same disk shape or circular in plan either with a finished edge, a fancy edge, or with a plain edge A and with a plain or fancy center B. This center may be blank and of fancy form, or it may have a suitable motto or advertisement thereon.

The bead C is an important feature of the a blank, as it is this portion thatis operated upon by the machinery. In my application for patent, filed June 14, 1902, Serial N 0. 111,708

I show a machine for which this blank is adapted. It is essential that this bead O of the blank should be uniform in every respect and annular in plan and concentric with the edge of the blankand that it should project from the face of the blank in annular ring form, leaving material enough to form characters in relief when operated upon by the machine.

I have found that in making the blanks it is preferable to form the blank with annular beads C on both faces and in identically the same relation to the blank. The object of this. is to prevent mistakes in feeding the disks to the hopper or feeder and to always present the blank so that it will be operated upon rightly regardless of the face presented. In machines into which the blanks are fed by hopper mistakes are ofttimes made by ignorant operators, and hence the necessity of a construction which cannot be improperly fed. Also by forming the bead C out from the face and concentric with the edge a perfect action and result is attained, and every disk operated upon will turn out perfect as far as the lettering is concerned.

What I claim is 1. A blank formed on one of its faces at a point within the bounds thereof with a raised "annular bead, said bead having a flat upper
